The online world is a noisy place. Currently, there are an estimated 450-million English-speaking blogs on the web. No matter which way you look at it, that’s a lot of content. Once you remove the copies, the spun articles and the god-forsaken article directories full of fluffed up awfulness, you’ll start to get a clearer picture of just how hard it can be to locate the guys you should be following.

Here are 7 of the smartest entrepreneurs online. These are the cream of the crop and all have something to teach you about business as well as life.

Mark Cuban is a billionaire entrepreneur (is this beginning to sound like his Shark Tank intro?) who is most well known as the outspoken owner of the Dallas Mavericks NBA franchise. Mark made his fortune during the dot-com boom and he’s as web savvy as they come.

Mark doesn’t post often; sometimes he goes a month or more without a peep. When he does blog though, it’s always worth reading. He covers a wide range of topics running the gamut from business, politics, sports, television, life and even – you guessed it – his beloved Dallas Mavericks.

Seth is a writer, speaker, entrepreneur and one of the smartest “big picture” guys in the world. Seth made his fortune with several small companies before starting one of the first online marketing companies in existence. Godin is probably most well-known for the creation of Squidoo – one of the most trafficked sites on the web – or one of his many books, such as:

“The Dip”

“Permission Marketing”

“Purple Cow”

“All Marketers are Liars”

As far as blogging goes, Seth’s Blog pretty much covers anything having to do with entrepreneurship, as well as marketing, life hacks, and ideas to help differentiate you from the crowd. The posting frequency has been very consistent lately with one or two blog posts most days. Most posts are short idea-type posts to spark your creative juices with others being quite long and informative.

Who doesn’t know Gary V? The author of New York Times best seller “Crush It” is probably best known as the founder of (no longer updated) Wine Library TV, a daily video blog covering wine, rants and the New York Jets. Gary is now a high-priced consultant on social media and web marketing as well as a speaker and the author of the follow-up to his smash success, “The Thank You Economy.”Gary is a true social media pioneer and was one of the most vocal proponents of building a personal brand via social media outlets.

Gary Vay-Ner-Chuk covers social media, online business and personal branding. The blog is updated regularly although it’s sort of a Tumblog format with a mash-up of pictures, text and video from various sources online – most featuring Gary V himself.

Tim Ferris is best known for his game-changing book, “The Four Hour Workweek.” Tim is also: the Chinese national kickboxing champion, an MTV break dancer (in Taiwan), a champion ballroom dancer, a speaker of five languages and a 180-pound sumo wrestler. Is it any wonder Newsweek calls him, “The World’s Best Guinea Pig?” As amazing as his achievements are, Ferris has some real business sense to go along with it and he’s been an entrepreneur, with several companies under his belt, for over a decade.

The Four-Hour Workweek blog is Tim’s personal home base, which sports the tagline, “Experiments in Lifestyle Design” – which is pretty accurate in describing the sort of content you’ll see. Although there isn’t a ton of business content, there is more than a fair share of content, which relates to life in general and can be carried over to the business world. There are also useful hacks on how to get your body and mind to perform to their full potential, which is certainly helpful in any business.

Kawasaki is a well-known blogger as well as a venture capitalist. He was also one of the marketing wizzes behind promoting the Macintosh computer back in 1994 and now is a Managing Director of Garage Technology Ventures, a Silicon Valley early-stage venture capital firm.

Guy doesn’t post often, sometimes he’ll go six plus months without an update, but he’s extremely active on Twitter. When he does posts, they’re always amazing and they cover topics ranging from social media and publishing, as well as wide-range of business-centric ideas.

Brian Clark is an ex-attorney and and offline business mogul who built three online businesses using online techniques. He is now the CEO of Copyblogger Media and one of the most well-known bloggers online. Clark’s blog, Copyblogger is one of the highest trafficked sites online according to Technorati as well as being in nearly every “Top” list for online marketing and copywriting. In short, it’s a blog you should have subscribed to a long time ago. Brian is also the entrepreneur behind the extremely popular content-marketing solution, “Scribe.”

Copyblogger is – at its core – a blog about copywriting. The content is largely there to teach you how to attract a larger audience, funnel leads into conversions through sales copy and just how to become a better and more persuasive writer in general.

This might be someone you’ve never heard of, but let me assure you that Dr. Cornwall is the real deal. He’s a co-founder of Atlantic Behavioral Health Systems as well as an author, or co-author of six books on the topic of entrepreneurship. Dr. Conrwall also teaches entrepreneurship at Belmont University and was the President of the United States Associate of Small Business and Entrepreneurship (USASBE).

Cornwall blogs about anything entrepreneur-related with a focus on the business side of things rather than the more idea-centric, lifehack approach of someone like Tim Ferris.

These entrepreneur-turned-blogger rockstars are a must-have for anyone serious in starting or growing a business. These are some of the best blogs online, and for the most part they’re written by (or under the guidance of) some of the biggest and brightest entrepreneurial minds of our time.
